 FIELD OF THE INVENTION The present invention relates to a disinfectant, and particularly to a weakly acidic disinfectant. BACKGROUND OF THE INVENTION Currently, the most widely used disinfectants are hypochlorite, chlorite or chlorine dioxide, which has the advantages of wide sterilization spectrum, low price and convenient use. It is about 8 and is alkaline. Hypochlorite, chlorite or chlorine dioxide dissolves in water under alkaline conditions to generate more hypochlorite ions, 0C plants, and chlorite ions, C10. There is a small amount of hypochlorous acid H0C1 and chlorous acid. The bactericidal effect of hypochlorous acid H0C1 is 80 times that of hypochlorite ion OCr. Similarly, the bactericidal effect of chlorous acid is much greater than that of chlorite. Therefore, in alkaline conditions, in order to achieve effective sterilization effect, it is necessary to Large concentration, generally the effective chlorine concentration is as high as about 1000 ppm. Due to the high concentration, the cost is increased, and it is inevitable that chlorine is released to produce strong irritating and corrosive effects on human skin, soft tissues and mucous membranes.

 Example 11

 Refer to Figure 1, the concentration change test of hypochlorite under different pH conditions.

 Take sodium hypochlorite as an example. Sodium hypochlorite is dissolved in water with a pH value of about 8. It immediately hydrolyzes out -OCr, H \ Na +, and the hydrolysis equation is:

NaOCl + H ₂ 0 → Na ⁺ + 0CT + HO— + 2H ⁺

 Hypochlorite ocr produces bactericidal effects.

 When the pH value is adjusted to 3-7 by adding acid, sodium hypochlorite is dissolved in the acidic aqueous solution, and stable H0C1 and Na + will be generated. The hydrolysis equation is:

 H +

NaOCl + H ₂ 0 ^ Na ⁺ + H0C1 + H0 "+ H ⁺ After testing, the bactericidal efficacy of H0C1 is 80 times that of OCl—. It can be seen that after adding an appropriate amount of pH regulator to hypochlorite, the present invention has a redox potential of + 800 ~ + 1100mv, making the aqueous solution weakly acidic. It produces stable H0C1 with strong sterilization ability, which greatly increases the sterilization effect.

 When the acid concentration in the aqueous solution is continuously increased to show a strong acidity, that is, when the pH value is less than 3, the H0C1 concentration decreases by the oxidation potential measurement, which proves that: H0C1 is unstable under strong acidic conditions. Therefore, it is verified that under weak acid conditions, PH3-7, preferably PH4-6, hypochlorite has the strongest bactericidal effect.

The following experiment can further prove the above test results. The method is to dissolve C1 ² in water, and its hydrolysis equation is C1 ² + H ₂ 0— HC1 + H0C1. Gradually add and subtract to gradually increase the pH value, and measure the Cl in the solution at different pH values. ^2. The concentrations of HOCK and 0C1—, the results are shown in Figure 1:

When the pH is 1, the solution is strongly acidic, the C1 ² content is above 70%, and the H0C1 content is less than 30%; when the pH is 2, the solution is strongly acidic, the C1 ² content is less than 30%, and the H0C1 content is 70%. When the pH is 3, the solution is weakly acidic, the C1 ² content is less than 10%, and the H0C1 content is about 90% or more; when the pH is 4-6, the solution is weakly acidic, the C1 ² content is small, and the H0C1 content About 99%;

 When the pH is 7, the solution is neutral, the OCr content is about 20%, and the H0C1 content is more than 80%; when the pH is 8, the solution is alkaline, the OCr content is more than 80%, and the H0C1 content is less than 20%; From the above test, it is proved that: when the pH is 3-7, the content of Η0Π is stable above 80%; especially when the pH is 4-6, the content of H0C1 is almost stable at about 99%.

 The above test results further prove that when the adjusting solution is weakly acidic, that is, when the pH value is 3-7, H0C1, which has strong bactericidal effect, exists stably.

 Similarly, the aqueous solution of chlorite and chlorine dioxide, under weakly acidic conditions, has stable chlorite acid with strong bactericidal effect, which has the same effect, so it will not be repeated.

 Example 12

 Test of H0C1 and OCr content of hypochlorite under different pH conditions.

 Real-eyelid method: Dissolve sodium hypochlorite in water to prepare an aqueous solution with an effective chlorine concentration of 1000 ppm, and adjust the pH value to test the percentage content of H0C1 and 0C1—

The results are shown in Table 1: Table 1 H0C 1 and 0C 1 content of sodium hypochlorite at different pH values

 Results from the tests indicate that:

 1. Test No. 3, when the PH value is 10-8, there is only less than 23% H0C 1 in the solution, and the concentration of 0C 1- is more than 77%.

 2. Test No. 4-9, pH 7.0-3.5, the concentration of H0C 1 in the solution is above 80%, and

The concentration of 0C plant is below 20%.

 Prove that more than 80% H0CL with strong bactericidal effect is stably present in the solution under weak acidic conditions

 Example 1 5

 Experimental study on the bactericidal efficacy of the chlorine dioxide of the present invention.

The solubility of chlorine dioxide in water at 4 ° C is 2000cm7 l00ml, which is about 5 times that of chlorine gas. It can be decomposed into HC 10 ₂ , C 1 ² and 0 ^{2 by} heat or light. Its disinfection characteristics in water are shown below several aspects:

1. Can kill pathogens and viruses in water.

 2. The effect of decolorization and deodorization is better, especially the effect of removing phenolic odor is better.

 3. The effect of precipitation of iron and manganese is better.

 4, can reduce the formation of harmful substances such as chloroform in water.

 5. Especially when ammonia is contained in the water, it does not reduce the chlorination and disinfection effects. This feature can be proved by the following tests: Chlorine dioxide is added to water containing 0.5 to 10 mg / L of ammonia, and it is measured after 2 hours at constant temperature. The content of chlorine dioxide is basically unchanged, which proves that chlorine dioxide does not react with ammonia. Therefore, the use of chlorine dioxide as a disinfectant is of great significance in water supply experiments.
